When a mark key of a remote control is pressed by a user during fast-forward reproduction of video images and audio sounds, a system control unit searches a position of a video image which is presumed as a scene change closest to and on rewind side from the position of the video image reproduced at the time the mark key is pressed. This search is performed, based on rate of change in amount of data (bit rate) of the compressed video data used per unit time to generate the video signals by a video and audio signal processing unit. The system control unit then sets, as a mark position, the position of the video image presumed as the scene change.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A video reproducing apparatus comprising: reading means to read video image-related data from a recording medium having the video image-related data recorded thereon; video signal generating means to generate video signals for reproduction of video images on the basis of the video image-related data read by the reading means; reproduction control means to control a process of reproducing the video images, using the reading means and the video signal generating means; operating means to perform setting operation for setting a mark position which is referenced by the reproduction control means as a starting position to start reproducing the video images; and mark position setting means to set the mark position in accordance with operation of the operating means by a user, wherein, in accordance with the setting operation for setting the mark position by the user using the operating means, the mark position setting means automatically sets, as the mark position, a position of a video image presumed as a scene change in video images nearby a position of a video image reproduced at the time the setting operation for setting the mark position is performed.
2. The video reproducing apparatus according to claim 1 , which further comprises scene change automatic search means to automatically search a position of a video image presumed as a scene change in the video images, wherein, in video images on rewind side from the position of a video image reproduced at the time the setting operation is performed, the scene change automatic search means automatically searches a position of a video image presumed as a scene change closest to the position of the video image reproduced at the time the setting operation for setting the mark position is performed by the user using the operating means, and wherein the mark position setting means automatically sets, as the mark position, the position of the video image presumed as the scene change, which is searched by the scene change automatic search means.
3. The video reproducing apparatus according to claim 2 , wherein the video image-related data read by the reading means are compressed video data, and wherein, based on rate of change in amount of data (bit rate) of the compressed video data used per unit time to generate the video signals by the video signal generating means, the scene change automatic search means automatically searches the position of the video image presumed as the scene change.
4. The video reproducing apparatus according to claim 3 , wherein, based on variation in presence and absence of audio sounds, the scene change automatic search means automatically searches the position of the video image presumed as the scene change.
5. The video reproducing apparatus according to claim 4 , wherein, based on rate of change in frames of the video images, the scene change automatic search means automatically searches the position of the video image presumed as the scene change.
